Safety precautions Definitions and Symbols

! DANGER

Indicates a potentially hazardous situation which, if not avoided, can result in serious injury or death.

! CAUTION

Indicates a potentially hazardous situation which, if not avoided, can result in minor to moderate injury, or serious damage of product.

: Indicates Prohibition

! : Indicates Compulsion

DANGER - Do not touch terminals while power ON. There is a

danger of electric shock and/or injury. - Be sure to install external safety devices outside of the

PLC like emergency stop circuit or interlock circuit.

CAUTION - Be sure that the rated voltage matches the power supply

voltage of the unit. Otherwise, there is a danger of breakdown and/or injury and/or fire.

- Only qualified personnel shall carry out wiring work. Otherwise, there is a danger of breakdown and/or injury and/or fire.

COMPULSION - Be sure to ground the unit. Otherwise, there is a danger of

electric shock and/or malfunction.

PROHIBITION - Do not attempt to modify nor disassemble the unit. There

is a danger of breakdown and/or injury and/or fire. - Do not connect or disconnect cable unless power has been

switched off or the area is known to be Non-Hazardous. (This unit is industrial control equipment for use in hazardous locations "class I, Division2, Groups A,B,C,D")

PLC Wiring Power Wiring

- Appropriate emergency circuitry, interlock circuitry and similar safety measures should be added to the system.

- Appropriate safety measures should be included in the system for unexpected breaking of wire or malsignal caused from instantaneous power failure.

- Applied voltage must be in the range specified in the manual. Otherwise, there is a danger of breakdown and/or injury and/or fire.

- Install external earth leakage breakers to avoid short circuit accident.

- In case of the following operations, turn off power. Otherwise, there is a danger of breakdown and/or injury and/or fire.

• Mounting or dismounting CPU and I/O modules. • Assembling cabinet or machine including PLC. • Wiring. - Install net filter specified in Table 1 or similar. The input and

output cable of the net filter should be separated as much as possible. Be sure to ground the net filter. Use shielded cable for input of net filter.

- A shielded and insulated transformer is recommended. - The basic and expansion unit should be connected to common

power source and powered up together as shown in Figure 1.

- Recommends installing a lightning arrester to prevent lightning damages.

I/O Wiring

- Be sure that the input/output voltage matches the specified voltage. Otherwise, there is a danger of breakdown and/or fire.

- Use shielded cable for relay outputs module, and connect shields to a functional ground for one side or both sides depending on applications.

- Route the AC power line and I/O lines separated as much as possible. Do not route both cables in a same duct.

- Route the I/O lines and data lines as close as possible to the grounded surfaces such as cabinet elements, metal bars and cabinets panels.

(1.02 Nm)

Common precautions - Use proper cable ferrules for terminals. Using improper cable

ferrules or connecting bare wires to terminals directly might result in fire.

- Do not turn on power, if the unit appears damaged. - Be sure to check all field wiring before PLC power on.

Otherwise, there is a risk of fire. - Do not attempt to disassemble, repair or modify any part

of the PLC. - Do not pull on cables or bend cables beyond their natural

limit. Otherwise, there is a risk of breaking of wire. - Check carefully your PLC program before operation. - Keep PLC modules in their boxes during storage and

transport.

*: Alphabet before (X) indicates version (A,B…).

Installation environment Avoid the following locations to install the PLC. - Excessive dusts, salty air, or conductive materials (iron

powder, etc.) - Direct sunlight. - Temperature less than 0°C or more than 55°C. - Humidity less than 20% or more than 90%. - Dew condensation. - Direct vibration or impact to the unit. - Corrosive, explosive or combustible gases. - Water, chemicals or oil splashing on the PLC. - Close to noise emission devices.

Application Manual Read the following application manual carefully to use the PLC safely and properly. Be sure to keep the latest version.

Installation / Mounting Base unit mounting

- Fix the base unit by four screws (M4, 20mm (0.78in.) length or more) or by DIN rail tightly.

- To operate PLC within the range of ambient temperature,

(1) Be sure to take enough draft space. (Top and bottom; 50mm (1.97in.) or more, right and left; 10mm (0.39in.) or more)

(2) Avoid mounting over heat generating devices such as heater, transformer, and high capacity resistor.

(3) When ambient temperature becomes 55 or more install a fan or cooler so that ambient temperature is less than 55.

- Avoid mounting inside the panel installed the high-voltage device.

- Mount 200mm (7.87in.) or more away from the high-voltage wire and the power wire.

- Avoid inverted mounting, vertical mounting, and horizontal mounting.

Item Description

USB communication port USB port supports gateway function (with EHV-CoDeSys) only. USB cable is not included with CPU package nor supplied by Hitachi-IES. Use a standard USB cable.

Serial communication port Serial port has both gateway function (with EHV-CoDeSys) and IEC programming function supporting Modbus-RTU master and general purpose communication. * Both a gateway / IEC programming function can be switched to RS-232C / RS-422 / RS-485.

[Note] Be noted that RD LED could light in a moment at power ON/OFF.

Ethernet communication port

Ethernet port has both gateway function (with EHV-CoDeSys) and IEC programming function supporting Modbus-TCP client/server. In addition, network variables are transferred to/from other EHV+ CPUs over Ethernet network.

RUN / STOP switch When this switch position is in RUN, CPU start executing program. At the same time, remote controlling is enabled, in which case, CPU is started or stopped by EHV-CoDeSys over communication. When this switch position is in STOP. CPU stops executing program. In this status, remote controlling is disabled.

Lock button Press this button to dismount. Module can be fixed firmly by a screw of M4×10 mm(0.39in.).

Front cover Open this cover when operating the RUN switch or replacing the battery. Keep the cover closed while the module is running. When the cover is opened, do not touch the printed wiring board.

Battery holder Battery Battery connector

[Battery] Following data are maintained by battery. (1) Data specified as VAR RETAIN and VAR PERSISTENT. (2) RTC (real time clock) data

[Note] - Battery has polarity. Check polarity in connecting the battery although opposite connection is mechanically

impossible. - Be noted that the battery is not connected with factory default to prevent unnecessary battery consumption. - When using the CPU module, check the battery and plug the battery connector to CPU as shown above. - Refer to the table on page 6 for the life of battery.

Replace the battery every two years even when total power failure time is less than the guaranteed value.

! Caution

Note the following matters for the communication port. (1) Do not connect Ethernet cable to the serial port of CPU module. This could cause damage the CPU or connected equipment. (2) In 100BASE-TX (100Mbps) communication of Ethernet, connection could be unstable due to external noise depending on cable

length, installation environment and etc. In this case, take following countermeasures. 1] Increase the number of times to retry in connected device. 2] Change Ethernet communication speed to 10Mbps.

(3) USB communication could be unstable under severe noise environment. Be sure to use short cable and route apart from power line or other communication cables.
